--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Martin Jambor <jamb...@gcc.gnu.org>: https://gcc.gnu.org/g:0be3a051c03965c5c0385b783837154902bc08fa commit r14-1998-g0be3a051c03965c5c0385b783837154902bc08fa Author: Martin Jambor <mjam...@suse.cz> Date: Tue Jun 20 18:15:22 2023 +0200 ipa-sra: Disable candidates with no known callers (PR 110276) In IPA-SRA we use can_be_local_p () predicate rather than just plain local call graph flag in order to figure out whether the node is a part of an external API that we cannot change. Although there are cases where this can allow more transformations, it also means we can analyze functions which have no callers at all, which is pointless. Moreover, it makes an assert of hint propagation trigger, which checks that we have looked at callers before processing hints that come from them. This has been reported as PR 110276. This patch simply adds a check that a node has at least one caller into the early checks and makes the node a non-candidate for any transformation if it does not. gcc/ChangeLog: 2023-06-16 Martin Jambor <mjam...@suse.cz> PR ipa/110276 * ipa-sra.cc (struct caller_issues): New field there_is_one.
